I am so darn confused. let me tell my story. Oct 7, 2009 diagnosed with metastatic pappillary carincoma. I had my total thyroid removed and a 5cm tumor that was attached to my caratiod artery, neck desstion. I had 131 rai-200 on nov. 17, 2007. it showed cancer in my left lypmph nodes too. I had my 6 month follow up in June 2010 and my thyroglblin is 12.3. I a second treatment of RAI-200. Thyriod scan is negative. Petscan is no abnormalitites. I asked the doc why is my throygulin is elevated. He says I am clear and he will see me in 6 months. I thought the thyrogulbin need to be undetectable. I am on 0.137 of synthriod for TSH suppression. I just dont understand. And he won't explain it to me. What the heck should I do...

I don't know if this is exactly accurate, but my dr told me that it can take up to a year for the thyroglobulin level to go down to nondetectable.

antibodies can certainly mess with Tg results...The goal is for Tg to be undetectable.

There are a few labs that a doc will order in our situation. Thyroglobulin (Tg) basically indicates presence of thyroid tissue in the body. It doesn't necessarily mean cancerous thyroid tissue, just thyroid tissue producing Tg. In some cases, patients have antibodies to thyroglobulin (TgAb). In my case, i had undiagnosed Hashimoto's which, I believe, commonly produces TgAb. The reason I asked if you had them is because if you do, it makes it harder to rely on the Tg number - it messes with the measurements and makes that number unreliable. In that case, a doc may assess a patient's status using a variety of tests, such as you had.

If you're interested in the labs, you might want to read this article at thyca.org. I found it helpful in understanding some of this stuff when i was diagnosed. http://www.thyca.org/thyroglobulin.htm

Thyca.org has a lot of other useful information!

I had a CT scan showing my Thyroglobulin up from 5.4 to 6.2. I have known iodine-non-responsive mets in my neck and lungs (largest 6mm). Doctor said the increase in thyro was "in the noise" range and wanted to see increase of up to 10 or higher before beginning any new therapies. He called for re-scan in 3 months, I asked for two and he agreed.
